Definitely nostalgic for you, I mean, I am a little bit too young to even know them when it was their time... make sure to have a lot of fun with them? :P
The hardware and software limitations should be a part of the nice memory instead of something that can shatter them...here, think about it, do people even complain of lags or unpleasant gameplay due to bad hardware in the past? In some ways they do their job even better than the computers we have now, lol.
Yeah... most of the crankiness with retro games is the terrible IUI... well, in these games it doesn't matter quite so much... but in Strategy or tactics games... the UI is pretty important... and things have been made sooooo much better in the intervening years!
